slept with my neighbour/friend/ex's friend/he has a girlfriend
So I was drinking at my friends house when he showed up just in time to give me a ride home and we've lived across the road from each other for quite some time now and we were friends in grade 7 until now... we're both 19. I had a great night with him we were up until 6 and woke up at 9: 30 to do it again. I went home and then we've been hanging out for the past 5 days talking about everything because he also is going out wiith this girl kaitlin which I found out the day after she has a baby which isn't his and I think they's been dating for a year, he told me they were going to break up when she got back from Mexico which is today, he told me the last time we talked he wasn't ready for anything and he just wanted to see how things panned out but I've never done the whole random things he's my 4th and I was in a relationship with the others, I really like him but I feel like I can do nothing . Also my ex boyfriend is good friends with him and I'm friends with Kaitlins cousin and sister it's so confusing please help lol I haven't talked to hime since last time either so what should I do ?
